1 Claim. (01. 44-9) This invention relates to compositions for use in internal combustion engines and pertains particularly to a composition designed to be introduced into the engine with the fuel.

In the operation of those motor vehicles which are required to cover relatively great distances and which are kept in constant use, suchas trucks and passenger carrying buses, considerable difficulty is had and time lost through the development of a condition known as vapor lock.

The present invention has for its primary object to provide a composition which will prevent the development of the vapor lock condition by 25 introducing into the engine through the fuel supply means, substances which are so combined as to lubricate the contacting surfaces of moving'parts such as valve stems, piston rings, and the like and maintain the engine temperature 30 below the point which is conducive to the development of the vapor lock condition above referred to.

Another object of the invention is to provide a composition which, in addition to functioning 35 in the manner above described, will facilitate the removal of carbon from the interior of the cylinder when the use of the composition isbegun and which will then operate to. prevent the development of carbon.

40 The present composition consists of the following ingredients combined in the appended approximate proportions necessary for the making of a fifty gallon batch of the product.

Kerosene gallons 27 ounces 44 45 on of mirbane (o. s. n)- gallons 5 ounces 60 Oil of creosote (U. S. P)- gallons 10 ounces 120 Turpentine gallons 2' ounces 44 Oil of cedar wood. gallons 2 ounces 44 Camphorated oil gallon 1 ounces '72 The foregoing ingredients are mixed preferably by adding the oil of creosote and oil of mirbane to the kerosene and then adding the turpentine, oil of cedar wood and camphorated oil in the order named. By this procedure a clear solution results whereas, if any other order of mixing is followed, the product is cloudy and unsatisfactory in appearance.

The composition is used by adding approximately one ounce to each four gallons of gaso line. It is thus fed into the motor vehicle engine with the fuel through the carburetor and in this way it is brought into intimate contact with the valves and the stems and with the walls of the enginecylinder where it will work its way down between the same and the piston rings.

Experiments with the composition have shown that with 'the constituents used in the proportions set forth, the kerosene will burn out and remove any carbon deposits which may be present in the engine cylinders and the other oils adhere to the metal parts and are only eliminated by a wearing out process and during this time they function to keep down excessive development of heat. It will thus be apparent that by the elimination of the carbon the cylinders will remain clean and the proper even contact of the piston rings with the cylinder walls will not be interfered with and the working of the oils in between the contacting surfaces permit the same to move without friction and consequently without the development of heat. Also, because of the free movement of the piston rings relative to the cylinder walls, a substantially perfect seal is maintained which prevents the loss of power.

The proportioning of the ingredients enumerated, in the amounts specified, makes it possible to attain the desired results without the development of smoke or the deposit of gum in any of the engine parts. It is particularly essential that the camphorated oil be held to approximately the amount specified so that this condition of smokiness and gumminess will not be brought about.

While it is probable that some variations may be made in the amounts of the other ingredients, it is necessary that the quantity of camphorated oil specified for a fifty gallon batch be used in order that no gummy deposit will be left or smoke developed.

I claim:

A composition to be added in small amounts to hydrocarbon internal combustion engine fuel for eliminating vapor lock conditions in internal combustion engines consisting of the following ingredients taken in the appended approximate proportions for the production of a fifty gallon batch:

Kerosene gallons 27 ounces 44 Oil of mirbane (U. S. P.) gallons 5 ounces 60 Oil of creosote (U. S. P.) gallons 10 ounces 120 Turpentine gallons 2 ounces 44 Oil of cedar wood gallons 2 ounces 44 Camphorated oil gallon 1 ounces 72 JOHN HOWARD ESSICK.
